Definition
TWO SETS PV AUTOMATIC SWITCHOVER—When the
process variable is GREATER than the value set at
prompt SW VALUE (Switchover Value), the controller will
use Gain #3, Rate #3, Reset #3, and Cycle #3 Time. The
active PID SET can be read in the lower display.
When the process variable is LESS than the value set at
prompt SW VALUE, the controller will use Gain #4, Rate
#4, Reset #4, and Cycle #4 Time. The active PID SET can
be read in the lower display.
Other prompts affected: SW VALUE
TWO SETS SP AUTOMATIC SWITCHOVER—When the
setpoint is GREATER than the value set at prompt SW
VALUE (Switchover Value), the controller will use Gain #3,
Rate #3, Reset #3, and Cycle #3.
When the setpoint is LESS than the value set at prompt
SW VALUE, the controller will use Gain #4, Rate #4,
Reset #4, and Cycle #4.
Other prompts affected: SW VALUE
GAIN SCHEDULING allows you to schedule eight user-
defined Gain segments applied over a user-defined PV
range. Enter Gain and PV values under Loop 2 Tuning Set
Up prompts. PBorGAIN selection in Control Set Up group
also applies.
ATTENTION Gain scheduling automatically disables
Accutune for this loop.
AUTOMATIC SWITCHOVER VALUE—This is the value of
Process Variable or Setpoint at which the controller will
switch from Tuning Constant Set #4 to Set #3.
Only appears when PID SETS selections 2 PVSW or 2
SPSW are selected.
LOCAL SETPOINT SOURCE—This selection determines
what your local setpoint source will be.
LOCAL SETPOINT—The setpoint entered from the
keyboard.
TWO LOCAL SETPOINTS—This selection lets you switch
between two local setpoints using the
SETPOINT SELECT key.
THREE LOCAL SETPOINTS—This selection lets you
switch between three local setpoints using the
SETPOINT SELECT key. LSP 3 is mutually exclusive
with RSP or Internal Cascade.
